From 3e16f92536334ccb464ed88cf4d8cc0dd43da106 Mon Sep 17 00:00:00 2001 From: Tony Lindgren Date: Mon, 14 Feb 2011 15:40:20 -0800 Subject: [PATCH] omap2+: Fix omap_serial_early_init to work with init_early hook The new init_early hook happens at the end of setup_arch, which is too early for kzalloc. However, there's no need to call omap_serial_early_init that early, so fix this by setting it up as a core_initcall.
